After reading this question I understand agrarian skies modpack generates the world with nothing in it.

I recently found a world seed with multiple small biomes very close to each other, an ideal world for me.

I want to re-use this world, but start again on agrarian skies (nothing in the world, HQM totally reset, thaumcraft reset, etc.).

I have tried:

  • Generating a new world and traveling to the exact co-ordinates of my old world. This seems to have different biomes (due to it being a new seed).

  • Copying my old world and attempting to remove all player added blocks manually. (this is far too time consuming, not an ideal solution, though possible if nothing else exists).

  • Copying the world and removing the region directory. (this seems to generate a new seed, rather than use the old seed and generate a new world).

Is it possible to generate a new agrarian skies world from my seed so that I have a blank world with all these small biomes?

If not, is it possible to take the old agrarian skies world directory and convert it into a blank one?

Or, is there a command to remove all player added blocks?


Extra info

This is on Agrarian skies multiplayer using agrarian skies v3.1.2 (I think).

I generate the world via the server startup.

Apologies for multiple questions, but I think they all relate to the same problem.

The world seed is 3922357017991451086, if it makes any difference.

I haven't used Agrarian Skies, I assume you can't just enter a world seed into the normal seed box when creating a new world?

If not, you're left with one of two options:

  1. If you already have a world with the correct seed, then use a utility like MCEdit to bulk clear out all blocks.
  2. If you have a world that you want to use, but it doesn't have the right seed, you can use a utility like NBTExplorer to view and edit the save file, and change the world seed.
  • This world is generated via a server for multiplayer if that makes any difference. I should have mentioned that, sorry. Thanks for the answer, I had forgotten about MCEdit. I will give it a try when I get a chance. – Matt Lishman May 3 '16 at 15:17
  • @MattLishman The only difference between a single-player and a multi-player world is that the dimensions are in separate folders (its own separate "world" in technical terms) – aytimothy May 6 '16 at 4:32
  • This works and allowed me to further edit the world as I saw fit. Thanks. However, for anyone looking to simply generate a new world from a world seed, use Commandhat's answer. That is the simplest. – Matt Lishman May 7 '16 at 11:11

When you're starting a Minecraft multiplayer server, you can add a setting to your server.properties file called level-seed: <data> to force a predetermined seed to be used regardless of world settings.

Watch out, though!

  • If you remove the level-seed tag, then the server may forget which seed is being used and retrieve a new one.
  • If you don't use a file editor that understands Unix newlines, your server.properties file might end up very screwy looking.

  • Thanks for the answer. This worked. However, I chose Brad's answer because it fit my specific requirements more. Anyone looking to just use the world seed should use this answer though, it's the simplest. – Matt Lishman May 6 '16 at 22:30
